Senior Network Engineer (IS&T)

Role Summary

This is a senior-level Network Architect / Senior Network Engineer role focused on planning, designing, and deploying large-scale SD-Access fabric and spine/leaf campus network environments. The position leads deployment readiness, configuration development, IPv4-to-IPv6 migration planning, and post-migration stabilization for enterprise network modernization initiatives. The ideal candidate brings hands-on implementation experience, strong troubleshooting skills, and the ability to translate high-level network architecture into detailed, repeatable deployment standards. Success in this role requires clear communication, disciplined documentation, and effective collaboration during complex or high-pressure migration activities.

Responsibilities

• Lead end-to-end deployment planning for SD-Access fabric, spine/leaf, and enterprise campus network modernization projects.
• Translate high-level designs into deployment-ready low-level designs, implementation plans, configuration standards, and site deployment models.
• Develop and execute phased IPv4-to-IPv6 migration strategies, including dual-stack, phased transition, and native IPv6 approaches.
• Create configuration templates for underlay and overlay routing, segmentation, policy enforcement, quality of service, and application-aware routing.
• Develop Method of Procedure documents, deployment runbooks, rollback plans, validation checklists, and post-cutover verification procedures.
• Identify deployment risks, define mitigation strategies, and establish success criteria for each migration phase.
• Provide real-time technical support during migration activities, pilot deployments, cutovers, and post-migration stabilization.
• Troubleshoot routing, segmentation, IPv6 connectivity, VXLAN, RADIUS authentication, wired and wireless access, and service restoration issues.
• Collaborate with engineering, operations, field deployment, project management, vendor, and stakeholder teams to drive successful outcomes.
• Review field feedback and improve deployment standards, technical documentation, governance processes, and operational handoffs.

Qualifications

• 8+ years of enterprise networking experience with demonstrated real-world implementation responsibility.
• Hands-on experience with SD-Access fabric, software-defined campus solutions, or large-scale spine/leaf network deployments.
• Proven ability to convert network architecture and design intent into implementation-ready documentation, configuration standards, and deployment runbooks.
• Production experience leading or supporting IPv6 deployments and migration initiatives.
• Strong knowledge of BGP, OSPF, underlay and overlay architecture, route redistribution, failover, and route control.
• Practical experience with VXLAN, EVPN-VXLAN, segmentation, VRFs, VLANs, and policy enforcement.
• Experience with RADIUS, network access authentication, and wired and wireless access scenarios.
• Ability to troubleshoot live deployment issues, validate service restoration, perform root-cause analysis, and communicate resolution steps clearly.
• Strong technical writing, stakeholder communication, structured troubleshooting, and scenario-based problem-solving skills.
• Experience with large-scale, multi-site network rollouts; Cisco Catalyst Center / DNA Center, Cisco ISE, Catalyst 9000, Nexus, Arista, Palo Alto Networks, Opengear, Python, Ansible, Terraform, or configuration templating is beneficial. Relevant education, training, certifications, or equivalent practical experience.
